Stands NOT included Reverse Wrap cabinet Instead of a flat-fronted speaker with a curving back, Bowers & Wilkins' cabinets are formed from one continuous curve, held together with a spine of solid aluminum. Fewer joins make for a stiffer, more inert structure and a curved front means less baffling around the drive units. So sound dispersion is improved, and cabinet reflection is reduced. Continuum cone Thanks to its composite construction, the Continuum cone avoids the abrupt transitions in behavior that can impair the performance of a conventional drive unit. The result is a more open, neutral performance that delivers voices and instruments with precision and transparency. Aluminum top-plate Every stereo model in the new 800 Series Diamond range has a significantly upgraded cabinet design with an all-new aluminum top section for even greater stiffness. The same design also provides a perfect mounting point for all-new Leather by Connolly cabinet detailing, with luxurious black leather for dark cabinets and light grey for lighter finishes. Crossover All stereo models in the new 800 Series Diamond range now use rear-mounted crossover designs mounted on stiff aluminum spines. This isolates the sensitive capacitors from the unwanted effects of air pressure within the enclosure and makes for a very effective heatsink to ensure optimum performance when in use. Leather by Connolly The top section of every stereo model features an aluminum top plate, covered in all-new Leather by Connolly trim. Bowers & Wilkins uses luxurious, full-grain black leather for Gloss Black and Satin Rosenut finishes, and a light grey leather for White and Satin Walnut.
